UNITED STATES PATENT FFIOP.

RAY H. MANSON, OF ELYRIA, OHIO, ASSIGNOR TO THE GARFORD MANUFACTURING COMPANY, OF ELYRIA, OHIO, A CORPORATION OF OHIO.

TELEPHONE.

To all whom it may concern:

Be it known that I, RAY H. Manson, a citizen of the United States, residing at Elyria, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Telephones; and I do hereby declare the following to be a full, clear, and exact description of the invention,

such as will enable others skilled in the art the telephone is in use, it is desired to have the hook switch lever and especially the hook part projecting outside of and accessible from the outside of the casing in order that the same may be operated either by the hand or by the receiver or other telephone part placed upon the hook. IVhen, however,

the telephone set is not in use, it is desirable to have the switch hook lever retired to a protected position where it will not be exposed to the knocks and blows which the set encounters in being transported. In the field service of the army the sets are dumped into wagons or trains where they are tumbled about'the same as any other equipment, coming in contact with various articles and encountering rough usage for apparatus of this type. Any exposed parts are apt to be injured. When used by linemen, the sets are likewise tumbled about, sometimes being dropped from poles or otherwise subjected to blows which injure any exposed apparatus.

In accomplishing the. objects of my invention I aim to provide a hook switch lever which may be moved to normal position with the hook part projecting outside of the casing and when'in such position movable to operate the switch mechanism. When in this position the hook switch lever is best maintained there by some means, such as a yielding device which permits the hook switch lever to be moved to a position Specification of Letters Patent. Patented A 4 1 916. Application filed October 23, 1913. Serial No. 796,752. r Y I where it is protected, for example, by the casing. IVhen in retired position I consider it best to provide means to prevent its operating theswitch mechanism, since it is not desired to operate this mechanism during the transportation of the telephone set.

Other objects and aims of my invention and the invention itself will be probably 7 better understood from a description of a particularembodiment of the invention.

Figure 1 is a' plan view of an embodiment. Fig. 2 is a side elevation with the switch hook lever thrust within the casing. Fig. 3 is a side elevation showing the switch hook lever with a portion projecting beyond the casing and the same operating the switch mechanism. Fig. 4: is a detailed View with the apparatus in the same position as shown in Fig. 3 except that the switch-hook levelis not operating'the switch mechanism. Fig. 5 is a detailed view showing a front eleva' tion of certain parts.

Referring now to the drawing and to the particular embodiment of my' invention illustrated therein, at 6 is shown a portion of a telephonecasing which is here illustrated as being made of wood, though any suitable material may be employed, such as metal. A switch mechanism is shown at 80 mounted in any suitable manner and preferably supported within the casing by a bracket 13, which may be screwed or bolted to the casing. I contemplate any suitable switch mechanism. In the form shown this consists of contact springs 9, 10 and 11 connected through insulating members 12 to the bracket 13 by suitable means, such as 7 screws 14.

The bracket 13 is here shown as consisting of an angle plate provided with a vertical portion 15 and a top or horizontal part 16". V

The horizontal part is provided with a projecting lug 17 to which the switch mecha-- nism is connected. A switch mechanism operating member consisting of a hook switch leveris shown at'20. This lever when in normal position projects through an opening 8 provided in the casing, so that the hook portion 21 is accessible from the outside of the casing, Where it may be operated by the hand or other means. A portion of the talking set may be suspended fromthe hook 21 moving the hook tothe position shown in Fig. 4: where the switch mechanism is unoperated. \Vhen this portion of the talking set is removed from the hook 21', the

hook is moved to the position shown in Fig.

3, operating the switch mechanism. This portion of the operation is well known to those skilled in the art and will not be described here in detail.

Suitable means are provided for moving This is shown here as a spring 22,

to which it may be attached by screws The other end 25 engages the lever when in normal position, as illustrated in Figs. 3 and 4. The spring 22 is under normally downward tension, so that it tends at all times to expand. constituting means for a holding the lever in the positions illustrated in Figs. 3 and 4, but yielding when the lever is thrust inwardly or to the rear, as illustrated in Fig. 2.

The lever is best pivoted, and in the form shown, a pivot is illustrated at mounted on the bracket 13, the switch hook lever being rotated about the member 30 when moved from the position shown in Fig. 4 to the position shown in Fig. 3. A lug 31 is also provided upon the switch hook lever for operating the switch mechanism. The

lever 20 is also provided with suitable means for engaging the pivot when n the position shown in Figs. 3 and 4-." This may consist of a second hook 33 facing oppositely to the hook 21. A socket or gap 35 is provided in the hook switch lever adiacent thehook 33 into which the pivot 30 fits, when in. the

position shown in Figs. 3 and 4. A second 7 gap or socket is provided into which the pivot 30 fits when the lever is in the position shown in Fig. 2. An elevation or hump 34: is provided on the lever between these sockets. I may arrange the hook 33 and L socket 35 as I have shown in the form illustrated so as to prevent the further withdrawal of the hook switch lever 20 from the telephone casing beyond the position shown in Fig. 3. though permitting the insertion of the hook switch lever within the casing.

If it is attempted to withdraw the hook fur ther from the casing than illustrated in Fig. 3, the hook 33 engages the pin 30 and is held, pre enting a further withdrawal;

The hook switch lever is adapted to be moved to a position where it is protected by the casing As here shown. it is moved within the cas ng, as illustrated in Fig. 2.

IVhere a wooden casing is used as I have illustrated. it is not necessar to move the hook switch entirelv beyond the inside wall of the casing. as I'mav simplv thrustit inside the outer side of the wall. as illustrated in Fig. 2. Under these circumstances, j 'I prefer to 'cut away a 'portion-o'f the wall f lever to a the casing.

4. 'In a device of the class describedthe combination of a telephone casing, a hook 2 of the casing, as illustrated at 100, in order that the end of the lever may be caught be- 3 tween-the fingers and withdrawn.

34 and into the socket '50., the :top of .thelug.

4.0 engaging the top 13 of the bracket and the bottom of the socket '50 engaging the pivot 30 preventing the lever from rising, so that it will not be possible to operate the switch. mechanism when the lever is in the retired position. illustrated in Fig. 2.

I have thus illustrated and described one embodiment of my invention. I do not, however, wish to be limited to this particue lar embodiment as I contemplate numerous and extensive departures therefrom without departing from the spirit of my invention which is described concisely in the claims.
